stm32f429 memory device problem

I am using stemwin memory device for my own stm32f429 board with 8Mbyte external ram. When i create a 320*240 memory device , the lcd is flickering, but when i create a 320*230 memory device it does not flickers. For stemwin gui configuration i am using the code below:

#define GUI_NUMBYTES  (1024) * 160
void GUI_X_Config(void) {
  static U32 aMemory[GUI_NUMBYTES / 4]; //
  // Assign memory to emWin
  GUI_ALLOC_AssignMemory(aMemory, GUI_NUMBYTES);
  // Set default font

when i try to increase the gui_numbyte more than 1024*160, the compiler gives error for memory. I think i can not increase the memory size for external ram. Any adives??
